Fig. 3 for fastening the trip at the desired angle Be it known that I, Wuncnmr H. Sonoorn MAKER, oi ltlontclair, in the county oi Essex and State of hiew Jersey, have invented is an e .arged plan view ofthe trip and its verse section of a portion of the trip, taken on the line ;z of Fig. Fig. st 1s a detall of the attachment on the reproduccr for coand preventing its loose movement around the pivot (26). By releasing this set screw, the trip may be adjusted and then held at the desired adjustment by tightening the screw. Theguide rods (28) run-in suitable passages formed in the body (10),-of the device. .This construction, as will be seen, permits the trip 25 to be .movedradially in or out, as the case may be, by in' or out movement of the bar 14 produced as" above described; and since the bars 28 are so guided as to move rectilinea'rly, the trip also moves rectilinearly, notwithstanding the angular motion of bar 14. The "screw 27, and the slot in block 27 in which that screw'works, ermits the trip to be adjusted with respect to the bar 14. p Theftrip (25) is provided with a track (29) which is curved in approximately an arc similiar to the'curvature of'the record lines on the disk. This track is at the true edge of the trip and inclines upward, termihating in ahook or stop '(30) on the upper end'of the track. .The track is beveled or slanted downward toward its inner end and this true edge whichis the high edge is formed with slight notches or kerfs (31),

the purpose of which will hereinafter ap-' pear. The trip also comprises a return track (32). This starts at the upper end of the track (29) and sweeps toward its opposite end in approximate parallelism with the track (29) and terminates in a. stop orjupturned end (33). The return'track (32) is also beveled or inclined downward toward its inner. edge.

Attached to the sound box or reproducer or-the arm which carries the same in any convenient manner is a bearing (34:) which an axle (35) isloosely arranged. This axle carries atone end a beveled wheel (36) and'at the other end a head (37). Two springs (38) are arranged on the ends ofthe axle. the wheel (36) is free torotate and is also allowed an axial movement whereby any inequalities inthe operation or adjustment of the various parts'of' the device are compensated for.

, In the operation of the device it is placed in the center of the recordand the thumb wheel (22) is tu ned to adjust the trip so that its track (29) is located at the point on the record where it is desired to stop the" operation of the machine. By manipulation" of the set screw (27) the trip shouldbe adjusted so that its track (29) inclines at" a very acute angle with the record lines on the disk. The operation of the machl'ne'ls now started and goes on in the usual way, the reproducer, carrying the wheel 36, being moved inward gradually in the well known manner, untilsaid wheel touches the trip 23; whereupon the sharp pdge of the wheel will engage in one of the notchesor scores 31 of said trip, and said wheel then mounts the The result of this construction is that track 29 of the trip, much as the wheels of i a railroad car sometimes mount a track rail, and the wheel rolls along the track 29 until it is arrested by the upcurved end or stop 30 of said track; The rise of the wheel 36' asit mounts the track 29 lifts the reproducer with its arm, needle andother attachments clear not permitted to have a'return or downward movement-which might reengage the needle with the record. In other words, these parts should be so shaped that the needle once clear of the record will be held up in that position. The beveled track and-the correspondingly beveled wheel (36)'insures that the engagement once effected is re-- tained, and that there be no danger of these parts slippingout of engagement-and allowing the 'reproducer to fall back with its needle on the record. If there is any oscillation relatively between the trip and the wheel (36'), and the wheel after reaching the stop (30) falls back down the track (29),

the wheel will then run off on the return track (32) which acts as a sort of switch. In this manner, the wheel is confined be-' tween the stops (30) and (33) and cannot he accidentally dislodged. Of course, the

reproducer may be lifted off the trip for a I renewed operation of the machine, It is, of course, to be understood that while I consider the construction here illustrated and described as preferable I am not, however, limited to the precise details shown and may vary the construction in numerous respects so long as the principles are retained. 'Having thus described my invention, wha

3. An attachment for sound reproducing machines comprising a member adapted for mounting on the record-carrier and provided with a track inclined upward in approximately the direction of normal travel of the sound reproducing point along the record, and thereby adapted for raising the sound-reproducing point from the record, in combination with a'member, other than the sound reproducing point of the machine, adapted for mounting on the sound reproducer, and arranged to engage said track at a suitable point in the operation of the machine, and to ride along said inclined track and thereby to raise the reproducing point from the record, said inclined track having, in addition to its before-mentioned inclination, a lateral inclination, the said member adapted for mounting on the sound reproducer having a corresponding lateral inclination and having a yielding support permitting motion of said member both toward and from the support.

4.
